Hammer versus press forming, kinetic energy vs pressure
Many thanks Pressed for your detailed explanation of all the factors involved in the comparison, I think I will stick to a hands-on comparison, considering the number of variables - but I like the sound of the 'force*time area under the pressure curve', I will keep that in mind. And thanks...- BenStorch

Hammer versus press forming, kinetic energy vs pressure
Thank you all for your comments, it is interesting to see how many perspectives there are on the subject. So it seems there is no straightforward equation to relate the two types of forces/loads applied in the two forming processes. I guess the difference in time, between the impulsive hammer...- BenStorch

Hammer versus press forming, kinetic energy vs pressure
Hello, I am trying to work out the difference in force exerted by either a press or a power hammer, for a sheet metal forming application. I worked out that the kinetic energy of a hammer is calculated as E = ½mv². Example of power hammer: 0.5 * 30 kg * (15m/sec)sq = 3.375 KJ How does this...- BenStorch
